A fluid regulating device comprises an actuator with upper and lower housing components. The upper and lower housing components are secured together at mating flanges via a plurality of fasteners. The upper housing component is formed with a vent to contain a relief valve, which exhausts fluid to the atmosphere under overpressure conditions. The upper housing component is constructed such that it does not require a pedestal or fins extending between the vent and the flange, which advantageously provides a completely unobstructed, continuous, ring-shaped flange for receiving and manipulating the fasteners during assembly and/or maintenance of the regulating device.
L'invention concerne un dispositif de régulation de fluide comprenant un actionneur ayant des composants de boîtier supérieur et inférieur. Les composants de boîtier supérieur et inférieur sont fixés ensemble au niveau de rebords d'appariement via une pluralité de dispositifs de fixation. Le composant de boîtier supérieur est muni d'un orifice pour contenir un clapet anti-retour, qui laisse échapper du fluide à l'atmosphère dans des conditions de surpression. Le composant de boîtier supérieur est construit de telle sorte qu'il ne nécessite pas de socle ni d'ailettes s'étendant entre l'orifice et le rebord, qui fournit de manière avantageuse un rebord en forme d'anneau, continu, complètement non obstrué pour recevoir et manipuler les dispositifs de fixation pendant l'assemblage et/ou l'entretien du dispositif de régulation.
